Florida lights are on the "to do" list ... and I would bet, when confronted with the "spider towers," we've all stood underneath and shot skyward ... I missed dead center symmetry by just a hair in that first one ... for sure a reason to go back to a beautiful setting ...

Believe those who search for the truth ...
Doubt those who find it ...

My first thought, upon seeing number 1, was Sanibel Island as well. I knew I was wrong when I saw number 2. You made me look this one up even after you said Marblehead. This isn't what I think of when I hear Marblehead. I was never a real skeletal tower fan until Hillsboro Inlet a few years ago.

Sanibel light is the oldest of this class of tower. It was built in 1884 and is different at the base then most of these pile towers. Here is a photo of Sanibel. Notice that the central column of the tower doesn't continue all the way to the ground. This is seen on Sanibel, Cape San Blas, South Fox Island, and Bellevue Rear Range. Chandeleur Island LA also had this feature. Lighthouse directory has a list of the onshore Skelatal towers and the classes they fit into. http://www.unc.edu/~rowlett/lighthouse/ ... etals.html Unfortunately some of the links don't work any longer.
